FABRIC.

To all whom, it 1v1/ay con/cern,.-

Be it known that we, ALBERT DE LAsKI and PETER D. THRorr, citizens of the United States, and residents of Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful Fabric, of which the following is a specification.

This invention relates to a fabric, and more particularly to a strong fabric for use in connection with pneumatic wheel-tires, lire-hose, &c., wherever resistance to high pressure and great endurance are required.

While we have chosen a circular-woven tubular fabric to illustrate this invention, we wish it to be understood that we do not limit the invention to such a style of fabric, but intend that it shall apply as well to a flat woven fabric and to a fabric whether the threads or yarns cross each other at right vangles or at an oblique angle.

In the accompanying drawings, Figure l is a View in perspective of a piece of circularwoven tubular fabric in which the weft and warp are both `formed of rubber treated twisted fabric. Fig. 2 is a similar View in which the warp is formed of rubber-treated twisted fabric and the weft of ordinary yarn or thread. Fig. 3 is an end view showing the weft formed of rubber-treated twisted fabric and the warp of ordinary yarn or thread; and Fig. A is a View of a portion of rubber-treated fabric, showing a strip partially severed therefrom and partially twisted to illustrate the manner of forming the weft and warp threads of the fabric, one 0r both.

In making the fabric we form the warp and weft threads or yarns, one or both, of rubbertreated twisted fabric. This fabric may consist of what is commonly known'in the art as friction-duck, or it may be made especially for the purpose, and consists, essentially, of

a fabric impregnated or faced with a rubber l Specification of Letters Patent. Application led July 1, 190'5. Serial No. 267,92@

Patented Dec. 12, 1905.

In manufacturing upon a commercial scale the rubber-treated fabric is slit into strips as it comes from the treating-rolls, and these are fed continuously to a twisting-machine to produce the yarn or thread required. In twisting this strip of fabric the rubber solution with which it is treated causes its twisted faces to adhere, and the twist is thereby maintained during the subsequent manipulation of the thread or yarn. When these threads or yarns have been woven into a fabric, the latter is submitted to a vulcanizing process, and the fabric becomes thereby one coherent mass of tough resilient material having great strength and durability and at the same time is so dense that air will not escape through it.

This fabric may alone form the wall of a tire or hose, or it may be used as one of the elements of a tire or hose, as may be found desirable.

By making the yarn or thread of twisted fabric which has previously been treated with the rubber solution we are enabled to insure the distribution of the rubber solution throughout the interior of the thread or yarn as well ason its surface, and, furthermore, the cost of manufacture is maintained at a low gure because of the simple structure of the yarn or thread and its tenacity in maintaining the twisted condition due to the friction between its walls. When vulcanized or cured, the threads are affected throughout their interior mass as well as along their exterior, so that the fabric becomes tough and pliable throughout its entire mass.

What we claim isl. A fabric having incorporated therein a of twisted rubber-treated fabric.

5. A fabric including threads formed of presence of two Witnesses, this 29th day of twisted rubber-treated strips, the said strips June, 1905.
